VACUUM: CLEANER.

Application filed April 15, 1920. Serial No. 374,113.

T0 all whom t may Concern:

Re it hnown that EDWIN A. Rican/ns, a citizen of the United States, residing at lililford, in the county of New Haven and State of Connecticut, have linvented certain new and useful Improvements in Vacuum Cleaners, of which the `following is a specification, reference being had therein to the accompanying drawings.

rllhis invention relates to new and improved vacuum cleaners of the type that is operated by hand, and having for its object among other things, to so design and con* struct the saine, that it may be composed of such few parts, that it may be economically constructed, readily assembled, and be highly efficient in its operation.

To these and other ends, the invention consists of a Vacuum cleaner having certain details of construction and combinations of parts as will be hereinafter described, and more particularly pointed out in the claim.

In the accompanying` drawings, to which reference is hereby made, and in which like numerals of reference designate like parts in both figures:

Figure 1 is an elevation of my improved vacuum cleaner complete, and

Figure 2 is an enlarged sectional view of a portion thereof taken upon line 2-2 of Figure 1.

The type of vacuum cleaner herein shown and described is substantially the same as that disclosed in U. S. Letters Patent No. 1,093,473 issued to me April 14, 1914 and consists principally of a vacuum cylinder and a piston cylinder 11, the open end of which is closed by a cylinder head 12, and in which a piston is manually operated by a handle 12. rllhe lower end of the vacuum cylinder 'l0 is preferably formed with threads or eorrugations 121-, and is closed by a conical head 15, 'having a flange 16 thereon, provided with threads or corrugations 17 similar to the threads or corrugations 14 and which engage with each other and hereby provide means to removably secure the head to the cylinder.

. Fixed to the conical head 15 is anozzle tube 18, having a nozzle 19 on the outer end thereof. lVithin the vacuum cylinder 10 is a dust bag 20 vwhich is closed at its upper end 21, and at its open end is secured in any preferred manner to a conical collar E22, which is held within the vacuum cylinder 10 by friction. The taper of the conical collar 22 is slightly exaggerated in the drawing for the purposes of illustration. it is customary to secure this dust bag within the cylinder by other than friction means', but for some purposes a frictional engagement is especially desirable.

Minor changes and alterations may be made within my invention, aside from those herein suggested, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of the appended claim.

Having described my invention, which I claim as new, and desire to secure by Letters Patent, is: l

A vacuum cleaner composed of a cylindrical receptacle of substantially uniform diameter and threaded at one open end which is atthe bottom of the receptacle when the same is in its operative position; a dust bag also having one open end; a conical collar projected into and held by friction within the open end of said dust bag which is also held by friction inside of said receptacle by reason of said conical collar, the larger end of which is adjacent to the threaded portion of said receptacle; a head secured to the threaded portion of said receptacle; and a nozzle tube secured to said head so that a portion thereof projects through said conical collar into said dust bag and another portion thereof projects outside of saidhead, said head and nozzle tube forming a closure for the open end of said receptacle.

ln testimony whereof, I have hereunto afiixed my signature.

EDWIN A. REEVES.
